It is a particularly productive soil of truffles. There are natural, controlled and cultivated ones. The first are those known by truffle hunters, which they would not reveal to anyone. The controlled ones instead are those in which the man works to promote the birth of truffles by planting at least 30 mycorrhizated plants. Finally, the cultivated truffle grounds are called so when the plants are at least 100 and therefore there is more intervention by the man as they are created specifically for the cultivation of truffles. In the controlled and cultivated “tartufaie”, only the owners can access them to collect truffles and do not have the obligation to have the license.
